'Could it be for love?
Illusions, mister Anderson, vagaries of perception! Temporarely constructs of a feeble human intellect trying desperately to justify an existence that is without meaning or purpose! And all of it as artificial as the Matrix itself...
Although only a human mind can invent something as incipient as love.'
- Agent Smith
And indeed, love borders to insanity and it's effects can be devastating, but I most definitely disagree it's a lie. Love remains one of my main sources for happiness in this life and all that have lost this faith are but empty shells dwelling in the darkness.
